APPARATUS FOR DISTILLING.

SPECIFICATION forming part of Letters Patent No. 454,061, dated J une16, 1891.

Application filed August 8, 1890.

To fallu/hom. t may concern:

Be it known that I, THOMSON McGoWAN, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Distilling; and I do hereby declare thefollowing exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same.

My invention relates to improvements in distilling and purifyingapparatus, more especially for treating hydrocarbons; and it consists incertain features of construction and in combination of parts hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of an uprightcylindrical still. Fig. 2 is a central vertical section of the upperportion of the still, the lower portion of the still being shown inelevation. Fig. 3 is a section on line ac, Fig. 2. Fig. 4 is an enlargedview in vertical section of the cylinder and attachments for holding thepurifying material. Fig. 5 is a transverse section of one of thesectional castings or rings of the cylinder. Fig. 6 is a plan of aportion of one of the sectional rings or castings, showing the annularinternal and external anges thereof. Fig. 7 a is plan of the ring thatretains in place the screen for supporting the purifying material. Fig.8 is a modification in vertical section of the cylinder. The still ofcourse may be of any desired form; but I prefer the cylindrical formshown.

A represents the still, and A the dome of the still. O represents atight diaphragm that divides the still into two compartments B B. Thesubstance to be distilled and purified is placed in the lowercompartment B. Diaphragm C is supported from beneath in any suitablemanner, and is also braced from above-for instance, as shown at C-topre- Vent sagging. The diaphragm has a central opening C2, connectingwith a cylinder or container D, the latter being supported by thediaphragm and being in open relation at the upper end with compartmentB. Cylinder orcontainer D is composed of hollow castings or rings D ofthe same diameter, and preferably three or four in number, placed oneyabove the other, as shown more clearly Serial No. 361,458. (No model.)

in Fig. 4. Each section or ring D has an annular external Iiange top andbottom d d, provided with holes, as shown m'ore clearly in Figs.4 and 6,for the reception of assemblingbolts d, that secure the rings orsections D' together, the bottom section or ring being also secured tothe diaphragm, preferably by riveting, as shown at fr in Fig. 2. One ormore of sections lD (or all, as shown in the drawings) have also anannularinternal flange d2 for supporting a coarse-wire screen E, thelatter being retained in place bya ringF, flange d2 and ring F beingprovided with holes d3 and f, respectively, for the reception of boltse, that secure these parts together. A screen E may also be provideddirectly over the opening in the diaphragm and supported by the latter.Upon the coarse screens E is preferably placed a fine screen ofwire-gauze E', and upon the latter is placed the purifying material.

G is a hood, usually of sheet or plate metal, located directly over thecylinder and supported in any suitable manner, preferably by bracketsG', end to the upper end of cylinder D and at the other end to the inneror under surface of hood G, as shown more clearly in Fig. 4. Hood G ispreferably provided with a series of openings, in which are secu redbent tubes G2, discharging' into the upper compartment of the still. Thefunction of the hood is to prevent any drippings or `condensed Vaporthat has resulted from condensation in compartment B from re-enteringcylinder D. lVith the construction shown more clearlyin Fig. 4 theopenings and bent tubes in the hood might be dispensed With, as theopenings between brackets G would be sufficiently ample for the escapeof vapor from cylinder or container D. Of course with the constructionshown in Fig. S, wherein hood G rests directly upon the cylinder D, theholes and bent tubes in the hood would be necessary.

II and I represent pipes for conducting of vapor and liquid,respectively, from the upper compartment of the still to condensers.(Not shown.) The vapor from the substance undergoing distillation passesinto cylinder or container D, wherein it is thoroughly purified, andthence passes up through the cylinder and through the bent tubes G2 andthe the latter being secured at one V IOO openings between brackets Ginto the upper compartment of the still.

Diaphragm C, as shown more clearly in dotted lines, Fig. l, is inclinedtoward dischargepipe I, so that any drippings or liquid resulting fromcondensation in the upper compartment of the still will flow toward pipeI and there be discharged.

In the distillation of a substance the vapor of which cannot readily bepurified during the distillation the purifying material and screens incylinder D can be removed and the vapor allowed to pass' up through thecylinder into the upper compartment B.

It will be observed that the construction of cylinder D and itsattachments is such that the component parts thereof can be readilySeparated for eleanin g, repairs, and other purposes.

J represents a pipe leading from the lower to the upper compartment ofthe still, through which pipe the vapor may pass when it is unnecessaryfor its purilication to pass the vapor through cylinder D, a cock orvalve J', that opens into the upper compartment being provided. Cock orvalve J has connected therewith suitable attachments and a rod leadingoutside the still, where a wheel j or other suitable device is provided,by manipulating which the valve or cock may be closed or opened.

Each compartment of the still is provided with a man-hole K, wherebyaccess may be had to the respective compartments for cleaning, repairs,and other purposes.

lVhat I claim isl. The combination, with a still an'd a diaphragm fordividing the still into two compartments, of a cylinder or containerlocated over an opening in the diaphragm and supported by the latter,said cylinder or container having one or more screens supported thereby,and having a perforated hood with bent tubes, substantially as and forthe purpose set forth.

2. The combination, with a still, of a diaphragm dividing the still intotwo compartments, said diaphragm having an opening', a cylinder orcontainer located over said opening, said cylinder or containersupporting one or more screens and a hood, and openings between the hoodand cylinder, substantially as and for the purpose set forth.

The combination, with a still, of a diaphragm dividing the still intotwo compartments, of a cylinder or containerlocatcd over an opening inthe diaphragm and supported by the latter, and a screen located directlyover said opening, the cylinder or container having a hood connectedtherewith and being in open relation with the two compartments of thestill, substantially as and for the purpose set forth.

4. The combination, with a still, of an inclined diaphragm locatedbetween the dome and bottom of the still, the diaphragm having anopening, a cylinder or container located over the hole in the diaphragm,said container or cylinder having one or more screens connectedtherewith, and dischargepipes leading from the still for conducting offthe products of distillation, substantially as and for lthe purpose setforth.

5. The combination, with a still, of an inclined diaphragm dividing thestill into two compartments, a cylinder or container for holdingpurifying material located over said opening, said cylinder or containerhaving a hood connected therewith and being in open relation with thetwo compartments ot the still, a discharge-pipe leading from the uppercompartment at a point just above the lower end of the inclining bottomand one located above this pipe for conducting off the products ofdistillation, and a pipe for conducting vapor directly from the lowerinto the upper compartment of the still, said pipe having connectedtherewith a cock or valve, the latter having suitable attachments foroperating said cock or valve from without the still, substantially asset forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 16th day of July, 1890.
